Book Synopsis Photophysics and Photochemistry of Poly(Di-n-Hexylsilane) in Room Temperature Solution by : J. Michl
Download or read book Photophysics and Photochemistry of Poly(Di-n-Hexylsilane) in Room Temperature Solution written by J. Michl and published by . This book was released on 1987 with total page 21 pages. Available in PDF, EPUB and Kindle. Book excerpt: Polysilane high polymers represent a new class of radiation sensitive polymers which are receiving considerable attention because of their curious spectroscopic properties and the development of a number of new applications. The lowest singlet excitation is sigma type, is localized in all-trans segments, and travels rapidly along the polymer backbone from shorter to longer segments. This energy transfer is competitive with fluorescence and polymer chain scission. The lengths of the low energy emitting segments of poly(di-n-hexylsilane) in solution have been estimated at 10-20 Si units. The reactions subsequent to chain scission are complex and poorly understood, but it is certain that complex silicon based radicals are formed. Keywords: Polysilanes, Solution spectroscopy, Theoretical studies, Polymer structure.

Download or read book Organosilicon Compounds written by Vladimir Ya Lee and published by Academic Press. This book was released on 2017-09-25 with total page 417 pages. Available in PDF, EPUB and Kindle. Book excerpt: Organosilicon Compounds: Experiment (Physico-Chemical Studies) and Applications, volume 2, also contains two parts. In its first part, Experiment (Physico-Chemical Studies), the application of modern instrumental tools (such as X-ray crystallography, 29Si NMR spectroscopy, UV-Photoelectron Spectroscopy, and other methods) for assessing the structures of organosilicon compounds is described. The second part, Applications, reviews the current research in the field of material science, specifically the use of organosilicon compounds in synthetic chemistry directed towards the creation of new materials. Organosilicon Compounds: From Theory to Synthesis to Applications provides a comprehensive overview of this important area of organic and organometallic chemistry, dealing with compounds containing carbon–silicon bonds. This field, which includes compounds that are widely encountered in commercial products such as in the fabrication of sealants, adhesives, and coatings, has seen many milestone discoveries reported during the last two decades. Beginning with the theoretical aspects of organosilicon compounds’ structure and bonding, the book then explores their synthetic aspects, including main group element organosilicon compounds, transition metal complexes, silicon cages and clusters, low-coordinate organosilicon derivatives (cations, radicals, anions, multiple bonds to silicon, silaaromatics), and more. Next, readers will find valuable sections that explore physical and chemical properties of organosilicon compounds by means of X-ray crystallography, 29Si NMR spectroscopy, photoelectron spectroscopy, and other methods. Finally, the work delves into applications for industrial uses and in many related fields, such as polymers, material science, nanotechnology, bioorganics, and medicinal silicon chemistry. Features valuable contributions from prominent experts cover both fundamental (theoretical, synthetic, physico-chemical) and applied (material science, applications) aspects of modern organosilicon chemistry Covers important breakthroughs in the field as well as with the historically significant achievements of the past Includes applied information for a wide range of specialists from junior and senior researchers (from both academia and industry), working in organometallic, organosilicon, main group element, transition metal, and industrial silicon chemistry, as well as those from interdisciplinary fields such as polymer, material science, nanotechnology
